About CSD-2A Series Gear Component Sets
CSD-2A is an ultra-flat strain-wave gearing family supplied as a circular spline, flexspline and wave generator for integration into a customer-designed housing. Available sizes and ratios cover maximum torque from approximately 12 to 823 newton-metres, with hollow-shaft diameters between 11 and 50 millimetres.
The short axial package reduces joint thickness and rotational inertia while retaining Harmonic Drive’s zero-backlash reduction and positioning accuracy. Because the component set does not include the output bearing or final housing, the machine builder can integrate bearings, encoders and cable routing directly around the mechanism. Applications include robot joints, semiconductor equipment and compact precision axes.
